摘 要：Apart from water,tea is the world’s most widely consumed *** is produced in more than 50 countries with an annual production of approximately 4.7 million *** market segment for specialty tea has been expanding rapidly owing to increased demand,resulting in higher revenues and profits for tea growers and the *** varietal identification is critically important to ensure traceability and authentication of premium tea products,which in turn contribute to on-farm conservation of tea genetic *** a set of single nucleotide polymorphism(SNP)markers developed from the expressed sequence tag(EST)database of Camilla senensis,we genotyped deoxyribonucleic acid(DNA)samples extracted from a diverse group of tea varieties,including both fresh and processed commercial loose-leaf *** validation led to the designation of 60 SNPs that unambiguously identified all 40 tested tea varieties with high statistical rigor(p0.0001).Varietal authenticity and genetic relationships among the analyzed cultivars were further characterized by ordination and Bayesian clustering *** SNP markers,in combination with a high-throughput genotyping protocol,effectively established and verified specific DNA fingerprints for all tested tea *** method provides a powerful tool for variety authentication and quality control for the tea *** is also highly useful for the management of tea genetic resources and breeding,where accurate and efficient genotype identification is essential.
